An administrator is troubleshooting a performance issue and observes that process A has a nice value of -10 and process B has a nice value of 10. Both are CPU-bound. What can the administrator conclude about how the kernel will schedule these processes?

Process B will receive more CPU time than process A because it is 'nicer'.

Both processes will receive exactly equal CPU time regardless of nice values.

Process A will receive more CPU time than process B under normal scheduling conditions.

The nice values have no effect on scheduling; only the process's state matters.

A developer is using `top` to monitor a misbehaving application and wants to see the nice value column. The default `top` output does not show it. What is the most direct way to display the nice value in `top`?

Press 'f' while in top and select the 'NI' column to add it to the display.

Press 'r' while in top to toggle the nice value column.

A root user wants to start a process with a nice value of -20, the highest possible priority. However, the administrator is concerned about system stability. What is the most appropriate way to proceed?

Use `nice ./critical_task` and rely on the default value.

Use `nice -n -20 ./critical_task` to start it with the highest priority.

Use `renice -n -20 -p 1` to set the init process to the highest priority.

Use `nice -n 19 ./critical_task` to avoid potential instability.

Part of the Topic 103: GNU and Unix Commands domain, which makes up ~19% of our current practice bank. Linux Professional Institute does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–11 in this domain), expect 1–1 from this objective — we provide 24 practice questions to prepare you well beyond it.
